Bosch Dishwasher water pipes scream when hot water is going through?

This says it is 'the drain is blocked.' So most likely it is frozen from what you posted. You could heat some water and pour into the bottom of the dishwasher to try and thaw the freeze. Got nothing to lose.

Yours might be under recall http://microsites.boschappliances.com/safetyrecall/dishwasher/popup_ModelList.aspx you might have a bad control board

Most dishwasher should be hooked up to a hot water line. They do recommend that you run hot water in your sink before you start running your dishwasher.

Hello Craig,
You can use Affersh dishwasher cleaner (link here) http://www.affresh.com/our_products/affresh_dishwasher_disposal_cleaner and to achive "Super hot" wash you can reset your hot water heater to a super high setting and the run a few cycles of the dishwasher....once done be sure to reset the hot water heater to the usual setting...also a very effective cleaner in the dishwasher is white vinegar ,try that along with setting the water heater higher

Good luck,
thanks for using Fixya.com

the hot water supply pipe should be 3/8 inch inside diameter

THE WATER GOING INTO MACHINE IS NOT HOT. LET WATER RUN UNIT IT IS HOT THEN START THE MACHINE. HEATER ONLY FUNCTION IS TO MAINTAIN THE HEAT , IT DOES NOT GO FROM COLD TO EXTRA HOT

The water connection is the smaller of the two and generally near the front of the machine, usually a threaded fitting on a electric solenoid will need a pipe to compression 90 fitting if its not already installed, it needs to be hooked to the hot water and that can be found on the left side going up to the sink faucet to be sure run some hot water and the side that gets warm is the correct one, you will need to turn off the water and install a T to connect the dishwasher if an unused shut off is not already there for the dishwasher. The drain line takes a hose and clamp and will hook into your drain iether through a dishwaser t or the disposal if you have one has a connection for it.

most bosch have the inlet valve at the end of the fill pipe and it has an anti-flood device.
try turning off the water, take off the fill pipe then reconnect it and see if this works.
taking off the fill pipe resets the anti-flood device

how do you disconnect the waste pipe from the back of a Bosch hydrosensor dishwasher

I am a recently retired appliance engineer of 20 years no that won't help, dishwashers only use one pipe cold water, check fill pipe for kink or low water flow rate filling up,if no problems then check heater element for open circuit, then check for any blockage with water outlet / filters and pump etc well somewhere to start to be going on with, if any of above helped rate me please,
